What is a prefab metal building kit?

Kits are custom-made to your specifications and engineered to meet (or exceed) your local building codes.

Why choose 'Red Iron' steel buildings?

American-made, I-Beam steel framing, custom-engineered in factories across North America.

A critical point for shops, commercial or personal, is the 100% usable, clear-span interior.

Steel buildings are incredibly durable. They are engineered to meet your local codes for wind, snow, and seismic loads. Manufacturers also offer structural and paint warranties of up to 30 years.

Precision engineerred steel buildings ensure your building fits together without a hitch the first time. The easy bolt-together installation enables fast deployment for DIY or contractor builds.

Another big plus of steel buildings is that you can expand for future growth, remove the end wall sheeting, pour a new slab, and add an additional 20 or 25-foot bay (or bays). Be sure to order 'expandable end walls' if this is a possibility.

Popular sizes provide varying square footage for storage, work areas, and vehicle storage. Larger structures add an office, a bathroom, or even a mezzanine for additional second-floor storage. Our suppliers work with you to ensure you get exactly the workspace you need at the right price.
